SPECIFICATION forming part of Letters Patent No. 414,840, dated November12, 1889. i Application filed December 21, 1883. Sen'al No. 115,294. (Nomodel.)

.To all whom t may concern.-

Be it known that I, HENRY A. HOUSE, of Bridgeport, Fairfield county,Connecticut, have invented certa-in Improvements in Paper- Box Machines,of which the following is the specification.

This invention relates to the manufacture of boxes or parts of boxesfrom blanks of paper or other suitable material; and it con- 1o` sistsof apparatus fully described hereinafter, and then particularly definedby the claims, for drawing the blanks into form, for carrying theblanks, stripping them from the dies, and presenting the latter properlyto the blanks.

In the drawings, Figure lis an elevation, in part section, of a machineembodying my improvements. Fig. 2 is a plan with the upper portion ofthe machine-such as the plungers zo for operating the formers and theguides for said plungers-removed. Fig. 3 is a perspective view showingdevices for guiding and delivering the formers. Fig. 4 is a section onthe line l 2, Fig. 2. Fig. 5 is a section elevation taken on the line 34, Fig. 2, looking toward the die feeding and guiding appliances. Fig. 6is the same as Fig. 5, showing the parts in different positions. Fig. 7is a former in section on an enlarged scale. Fig. 8 is a perspectiveview, on an enlarged scale, of one form of box made by this machine;Fig. 9, an end elevation, and Fig. l0 a detail, of the driving-hub,showing particularly the stop.

The machine as illustrated in the drawings 3 5 is designed to draw up orform blanks offpaper or other material upon blocks or formers forcedthrough a die of corresponding shape and carrying between them theblanks, the projecting edges of which are turned up against the formersto constitute the iianges as said formers pass through the die. The fulldescription of this operation will. be found in Letters Patent No.206,686, issued to me November 5, 1878, and need not be here repeated.

The main object of the present invention is to deposit the formersproperlyupon the blanks, and to then move the blanks and formers throughthe die, rake off the boxes,

5o and again deposit the formers upon other blanks, continuing suchoperation automatically. For such purpose I employ a machine in which isa blank-carrier, a device for depositing the formers successively uponthe blanks, a plunger for forcing the formers through the die, aconveyer for carrying the formers from the die, and a feeder forcarrying the formers to the depositor, and a discharger, whereby theflanged boxes are stripped from the formers. I have embodied 6o theseseveral devices and appliances in machines differently constructed, andhave used such devices and appliances constructed in different ways, andwill now describe in de tail one form of machine which l have found mosteffective.

The frame of the machine is illustrated -sufficiently to show thearrangement of essential working parts thereon, and supports a table A,guides B B., between which slides 7o a head C, carrying a plunger C anda holder or tubular die A', open at both ends, the upper end or mouth.being level with the face of the table. The die and plunger conform tothe shape of the former D, a series of which are used, said formerscorresponding in shape to the boxes to be made. Each former has grooves16 at the sides, and a central stripping-plug h, terminating in a disk hat the lower end, both fittingcorrespondingrecesses 8o in the former,and a spring h2 serves to keep the parts normally in the position shownin Fig. 7.

To permit ready alteration of parts, as different styles of boxes are tobe made, the plunger O is screwed detachably in the head, the die has aremovable center tube c, bearing upon a bottom piece a, which rests upona ange a of the outer casing a2 of the die; and it may be here statedthat the outer cas- 9o ing a? is hollow to permit the passage of acurrent of steam or hot water. The upper die-plate a3 has a centralflanged opening, is removable, and rests upon the tube c, which latterconsists of two or more sections bolted together to facilitateconstruction; The open ings in the plates c. d3 and in the tube c willcorrespond to the forms of the former, these parts being of coursechanged with every change of form or dimensions in the boxes to roo bemade. The space between the tube c and outer casing is lfilled withshot, pebbles, or

other granulated material, constituting a mass which will retain theheat, while permitting a ready change of the parts.

In making the boxes a blank is brought above the mouth of the die, aformer is deposited upon the blank, the plunger then descends and pushesdown the former until its upper face is level with the table. Anotherblank and former are then brought into position and forced downward bythe plunger, and so on, one former forcing another through the die. Theblanks are rectangular, as shown in Fig. 2 in dotted lines, and are heldin a tube X above the face of the table A, (see Fig. 5,) and a plate Eslides back and forth in guides Ll 4, Fig. 2, upon the face of thetable, and has an opening or slot which is successively brought beneaththe tube X, so as to receive the lowest blanks, and then above the mouthof the die A a stop 2, arresting the blank y (dotted lines Fig. Ll) inits upper position. A plate F extends between the tube X and the mouthof the die, partly covering the sliding plate E, and serves as a restfor the formers successively depose ited thereon, each former being then(as or after the blank is carried above the mouth of the die) slid intoposition upon the blanks, a rectangular guard G open at the front sidereceiving the former and guiding and holding it in proper position untilthe plunger descends. The guard G of course corresponds to the shape ofthe former, and is therefore detaehably secured in its position abovethe plate F.

The formers are delivered in proper position upon the plate F by deviceshereinafter described, and are moved over the plate into the guard by areeiprocati'ng arm H, secured to a slide H,which is reciprocated byhereinafter-described devices between guides 5 5 upon the face of thetable, the arm lAI being carried to a forward position, the former thenbeing deposited upon the plate F, and the arm ll then moving back untilin contact with the guard G, thereby carrying the former into saidguard.

To prevent any injuries should the plunger descend when the former isnot in the proper position, I use a stopping device, (see Figs. 2, E),and 10,) whereby the operation of the machine is suspended, unless theformer is earried to such a position as to move outward a pin d to apredetermined extent. As shown, the pin bears upon a rod d', carried byan arm d2 upon a shaft d, which has secured to its upper extremity ashort arm d". This latter arm bears against a similar short arm di onthe shaft d, which carries a trip-dog (Zion its outer end. Thedrive-wheel D2 is journaled loosely upon the shaft D3, and but for theclutch D would revolve independently of said shaft. The clutch D4 is asemicircular rod fitting in a corresponding groove in the shaft D3, andwhen locking the wheel one of its corners projects within a notch d inthe hub of said wheel.

d is an arm extending outward from the cluteh-rod and held in its normalposition by a spring d1". Now, as the trip-dog (17in its normal positionis within the field of rotation of the arm dg, it is obvious that unlesssaid dog be removed without said field it will trip the clutch, therebystopping the shaft and consequently all the operating mechanism of themachine, while the driving-wheel is left free to revolve. By the formersD coming to their proper position relatively to the plunger theabove-described mechanism is operated and the trip-dog thrown withoutthe field of the clutch-arm during every revolution of the latter justbefore it reaches said dog. Thus the machine continues to operate. Aseach former with the box molded thereon drops from the lower end of thedie A', it falls upon a belt-carrier I, passing around guide-pulleys Gand extending in an inclined position, so as to deliver the formers uponthe platform J, the carrier being provided with stops or lugs 7,arranged to pass between fingers 8, extending from the platform J, sothat the forlners will slide over said fingers to the platform as thelugs move between the fingers and descend in passing around the upperpulley. Each former as it passes onto the platform strikes a pin 9,projecting from a slide K, which is reciprocated by a rotary shaft K andpitman 12, so as to carry the former forward as soon as it is deliveredby the carrier I to a position designated by the letter V upon a plateL, which slides back and forth between guides 10 10, and is recessed inthe upper face to receive springtongues 11 12 1.3. As the plate L iscarried to its extreme left position in the direction of the arrows,Fig.2,it slides beneath the former D, held stationary by the pin i), untilthe end of the tongue 11 passes ont from beneath the former and bearsagainst the side thereof. rlhe plate L then slides to the right untilthe former is in the position shown at Y, when the plate again slidesback to the left beneath another former deposited thereon in theposition V, the former at the point Y beingheld in position by contactwith a stop f upon an arm f extending from a shaft f2, rocking inbearings 14. As the plate L moves to the left, the tongue 12 springs up,and when the plate is carried to the right the end of the tongue,striking the former at the position Y, carries it farther to the rightuntil it strikes the bent end g of an arm g, extending from the shaftf2, being then in the position Z. As the former approaches the positionZ, the grooves 1G receive the guide-edges e e of two plates M M',secured a short distance above and parallel to the platform J andexte11ding'for\val'd over the plate F upon the table A. The former isprevented from moving to the left after it reaches the position Z bypressure of springclamps 17 17, secured to theplates M M and receivingthe former between them, so that the former remains in place while theplate L passes wholly from beneath it, when a plun- IOO IIO

ger N, carried by the head C, will descend, and, striking the plug h,will force the box from the former into a chute O, which will conduct ittoa suitable receptacle. When the plate L again moves to the right,there will be three formers in position above it at the points V 'Y Z,(indicated in the foregoing de-4 .scription,) and each will be moved onestage to the right, the end of the tongue 13 striking the former at Zand carrying it to a position U, over the plate'F, in line with themouth of the die A, a position which is defined by a stop-arm 18,secured to the plate M. The outer section M3 of the plate M `is pivotedat 19 to the said plate, and a spring 20 tends to draw the section nearthe end of the plate M, so as to hold the former in position, theguideedge e being reduced upon the section M2 and entirely removed atthe opposite point upon the plate M, where a vertical plate serves as abearing, against which the former is clamped by the action of the spring20. There is also a vertical blade il upon the section M3. The sectionM2 is provided with an arm j, which extends downward and carries ascrewpin j', so that as the arm H moves to its eX- treme forwardposition it will strike the said screw-pin, swing the section M2 awayfrom the plate M, and allow the former to drop upon the plate F, overwhich it will be slid into the guard G as the arm His carried backward.The plate L is reciprocated by the revolution of a crank P, carried upona shaft 7a at its lower end, and-connected by a pitmau 7c to aA stud k3,extending from the plate L. It will be seen that the operation of theplate L and its tongue results in carrying each former by threesuccessive stages from the position V, in which it is left by the iinger9, to the proper position U above the plate F, another former beingcarried upon the plate L by the slide K as that previously deposited ismovedforward one stage. A stop-finger g2 may be carried by the arm g todefine the forward position of the formers at the point Y, and the arm gis lifted to carry the stops g g3 out of the way at the' properintervals by a cam m, having lugs which are brought in contact with anarm m upon the shaft f3.

To prevent the turning or misplacement of the formers after they areplaced upon the table, I sometimes use'a swinging guide Q with sideianges, which yield as the former passes beneath it, the side iiangesdirecting the former as it moves onward.

I will now describe suitable lnech anism for reciprocating the head C,plunger N, slides E and H, and for turning the cam m and pulleys 6 6.The shaft D3 is journaled in the uprights B B', and the driving-wheel D2is loosely mounted on said shaft, as before explained. On the other endof this shaft is a cog E3, which meshes with a cog F3 on the shaft G3 ofthe eccentric plunger-rod H3. This shaft G3 is jcurnaled in the uprightsB B', and has on the extreme inner end a balance-wheel I3, andimmediately beyond the cog F3 a beveled gear-wheel J3, which lattermeshes with a beveled gear K3, secured at the end of an upright shaftL3, journaled in bearings supported by the upright B. v

The construction and operation of the eccentric plunger-rod H3, which ispivotally connected to the sliding head C, is very ordinary, and is thesame as in the usual power-press.

M3 is a shaft, journaled between the uprights B B and having on theinner end a cog N3. Journaled on a short shaft O3, extending from theupright B, is an intermediate cog P3, meshing, respectively, with thecogs F3 N3, so that it will be readily understood that motion iscommunicated to the shaft M3 from the power-shaft D3.

Mounted on the shaft M3 are two cams Q3 R3, and pivotally hung on across-rod S3, extending between the uprights B B', are rods T3 T4, whichlatter have pins 0c y projecting across and against the edges of saidcams. The lower ends of these rods are connected to the slides E H bypitmen x3 @/3, pivoted, respectively, to said slides and rods, so thatit will be clearly seen that the swinging of said rods to and fro willcause the reciprocation of the slides. As the cams Q3 R3 revolve, theywill act directly against the pins y', thereby effecting the swinging ofthe rods T3 T4. The return movement of said rods T3 T4 is accomplishedby means of coil-springs 74E 75, which are secured at their ends,respectively,to the said rods and the uprighhB. The proper timing of thereciprocation of the head C and the operation of the slides E H is ofcourse a matter easily effected by the diameters of the severalcog-wheels. The lower end of the shaft L3 is provided with a beveledgear U3, which meshes with a similar vgear V3 on the end of the shaftK', thereby imparting motion to the latter. On this shaft K. are alsobeveled gears W3 X3,which mesh, respectively, with similar gears Y3 Z3on the ends of the shafts a? and 7c, thus giving rotation to the pulleysG and the crank P, for the purpose hereinafter explained. The plunger,being carried by the head C,willreciprocate with the latter and forceIthe plug from the former, as heretofore set forth.

I do not limit myself to the precise construction of parts set forthforcarrying the formers, as they may be varied without departing fromthe main features of my invention. For instance, the formers may bepushed forward from a plate upon which they are successively dropped,the movement of one shoving forward the others in Contact with eachother, and sliding upon a way inclined and curved to carry them to theproper positions below the discharger N and above the plate F. I havealso used other appliances for this purpose. Other appliances may alsobe used for carrying thel blanks successively over the die, or theplunger may carry a knife, which cuts off the Yblanks successively froma strip fed over the die.
